Bye bye

A young boy in a red and blue suit rides a futuristic motorcycle through space, smiling and waving, then appears in a control room, shouting and gesturing excitedly at a console. The scene shifts to a dimly lit room where two boys stand facing each other, one with a large head and the other with spiky hair, before cutting to a classroom where a boy with spiky hair sleeps at his desk while another boy stands behind him.
